BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a fixing device, and more particularly to a fixing device of a toilet cover.

2. Description of the Prior Art

European Patent Publication No. EP1199020B1 discloses a toilet seat assembly installed on a toilet ceramic body. The toilet seat assembly comprises a damper device, an adapter, and a fastening device. The fastening device is fixed on the toilet ceramic body. The fastening device is provided with a shaft head. The adapter is connected with the damper device. The damper device is used to support the pivotal turning of the toilet cover, namely, the toilet cover is installed on the damper device in a pivotal way. The adapter is formed with a radial blind bore for insertion of the shaft head of the fastening device.

The toilet seat assembly limits the horizontal and vertical movement of the adapter and the damper device as well as the turning of the adapter and the damper device through the shaft head of the fastening device to be inserted into the radial blind bore of the adapter. The limit displacement mechanism is by means of cooperation of the shaft head of the fastening device and the radial blind bore of the adapter, namely, the shaft head of the fastening device is inserted in the radial blind bore of the adapter.

Chinese Patent Publication No. CN203828832U discloses a structure used for installation of a toilet cover and a ceramic toilet. The structure comprises a fixing base disposed on the ceramic toilet. The fixing base is formed with a positioning hole. The middle of the side wall of the positioning hole is formed with an accommodation trough. A screw nut is accommodated in the accommodation trough. A fixing member includes a fixing rod and a fixing head located at one end of the fixing rod. The fixing rod is provided with threads. The fixing rod is inserted into the positioning hole and screwedly connected with the screw nut. The circumferential edge of the fixing head is provided with an engaging portion which first protrudes and then concaves. A positioning spring is secured on the toilet cover. The positioning spring includes at least two leaf springs corresponding in shape to the fixing head. The leaf springs hold against the fixing head.

The structure used for installation of a toilet cover and a ceramic toilet limits the horizontal movement of the toilet cover by means of the engaging portion of the fixing head to cooperate with the arc protrusions of the two leaf springs. However, the engaging portion is an arc trough in cooperation with the arc protrusions of the two leaf springs to limit the horizontal movement of the toilet cover. When the toilet cover is turned, the arc surfaces are easy to slide away each other. In addition, the positioning spring has a complicated structure. The arc engaging portion and the arc protrusion are parallel axially. During the turning of the toilet cover, the arc engaging portion applies a radial force to the arc protrusion. The direction of the radial force and the elastic direction of the arc protrusion to clamp the fixing member are opposite to each other, so they may slide away.

Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

As shown in FIG. 1 to FIG. 6, the present invention discloses a fixing device of a toilet cover. The fixing device comprises an insertion pin 1, a fixing seat 2, and an elastic clip 3.

The fixing seat 2 is installed on a toilet (not shown in the drawings). The fixing seat 2 is provided with a through hole 21. As shown in FIG. 1, the through hole 21 is disposed on the fixing seat 2 in a raised manner. The elastic clip 3 is installed in the through hole 21.

One end of the insertion pin 1 is connected with a turning member 4 which is installed to a toilet cover 5. The turning member 4 generally includes an adapter and a damper. The damper is installed on the adapter. An outer cover of the toilet cover is pivotally connected with the adapter. An inner cover of the toilet cover is pivotally connected with damper. One end of the insertion pin 1 is installed on the adapter. This is an existing structure, and won't be described hereinafter.

Another end of the insertion pin 1 is defined as an insertion end 11. The insertion end 11 is provided with an engaging groove 12. The insertion end 11 of the insertion pin 1 is inserted into the through hole 21. The elastic clip 3 is radially engaged in the engaging groove 12 to limit the horizontal movement of the insertion pin 1.

Preferably, the elastic clip 3 has a U shape. The U-shaped elastic clip has a simple configuration and can be processed conveniently to save the cost, and provides a better clamping elasticity. The insertion pin 1 is clamped by the U-shaped elastic clip 3. Furthermore, The U-shaped elastic clip 3 includes a curved bottom portion 31 and two side portions 32. The elastic clip 3 has a U shape. The two side portions 32 of the U-shaped elastic clip 3 are radially engaged in the engaging groove 12.

In this embodiment, the circumferential edge of another end of the insertion pin 1 is formed with the engaging groove 12. The engaging groove 12 is an annular groove.

The elastic clip 3 of the present invention is radially engaged in the engaging groove 12. The insertion pin 1 is clamped and positioned by the elastic clip 3 so as to limit the horizontal movement of the insertion pin 1. The elastic clip 3 is intersected with the insertion pin 1. During the turning of the toilet cover 5, the force applied to the elastic clip 3 by the insertion pin 1 is in an axial direction, not in a radial direction. The radial elasticity of the elastic clip 3 to clamp the insertion pin 1 doesn't be counteracted, such that the elastic clip 3 is engaged in the engaging groove 2 more stably.

For the insertion pin 1 to be inserted in the through hole 21 and the elastic clip 3 to be engaged in the engaging groove 12 conveniently, the insertion end 11 of the insertion pin 1 has a hemispherical end portion, as shown in FIG. 2, so as to reduce the frication when the insertion pin 1 is inserted in or pulled out of the through hole 21.

The fixing seat 2 is provided with an installation seat 6. As shown in FIG. 5, the elastic clip 3 is installed on the installation seat 6. The installation seat 6 is formed with a receiving hole 61. When the insertion pin 1 is inserted in the through hole 21, the insertion end 11 of the insertion pin 1 is inserted in the receiving hole 61 and the elastic clip 3 is radially engaged in the engaging groove 12.

The installation seat 6 is provided with two limit blocks 62 at two sides of the receiving hole 61. One of the limit blocks 62 is located at the bottom of the U-shaped elastic clip 3, and the other of the limit blocks 62 is located at the opening of the U-shaped elastic clip 3. The middle portion of the U-shaped elastic clip 3 is engaged in the engaging groove 12, enabling the elastic clip 3 is installed more stably.

In this embodiment, the fixing seat 2 includes a base seat 22 and an upper seat 23. The installation seat 6 is disposed between the base seat 22 and the upper seat 23. The through hole 21 is disposed on the upper seat 23. The fixing seat 2 further includes a decoration cover 24. The decoration cover 24 is installed on the upper seat 23.

When the fixing seat 2 is secured to the toilet as shown in FIG. 1, the fixing seat 2 is provided with a screw hole 25. The toilet is formed with an installation hole (not shown in the drawings). The installation hole is provided with an expansion screw 26. A screw 27 is inserted through the screw hole 25 and screwed to the expansion screw 26.
